JavaScript could work too

Are you serious?.... statcounter and GA are javascript based and collect most of the information via their JS code. Not only it "can work too", it is by far the best way of collecting user agent information (including installed plug ins etc.) and interacting with the viewer.

I am really surprised to hear such statements from people "managing 100's of websites".
